A Geometrical Derivation of a Family of Quantum Speed Limit Results
Benjamin Russell, Susan Stepney
We derive a family of quantum speed limit results in time independent systems with pure states and a finite dimensional state space, by using a geometric method based on right inva…

Zermelo Navigation in the Quantum Brachistochrone
Benjamin Russell, Susan Stepney
We analyse the optimal times for implementing unitary quantum gates in a constrained finite dimensional controlled quantum system. The family of constraints studied is that the per…
